Officers with the U.S. Customs and Border Protection seized what appear to be fake novel coronavirus, or COVID-19, tests at the Los Angeles International Airport, the agency said Saturday.
The agency called it a "significant interception, at a time when the U.S. is in the midst of a National Emergency."
The seized shipment of fake tests was turned over to the U.S. Food and Drug Administration, according to CBP.
What to know about Coronavirus:
Dr. Anthony Fauci, head of the National Institute for Allergies and Infectious Diseases, admitted Thursday the U.S. health system has struggled with getting testing up and running.
He added: "The idea of anybody getting [a test] easily the way people in other countries are doing it, we're not set up for that. Do I think we should be? Yes. We're not."
There are more than 155,000 confirmed cases of the virus in at least 140 countries, according to a case count by Johns Hopkins University. In the U.S., at least 56 people have died and more than 2,500 have been infected.
